Title: Improvements in or relating to tipping vehicles
IPC: B60P7/04
Filed: 1925-04-29
Abstract: 255,940. Turton, T. F., and Du Cros, Ltd., W. & G. April 29, 1925. Operating vehicle doors by tilting of vehicle and by springs and weights.-A tipping vehicle comprises in combination a hinged lid, the hinge axis of which is parallel to the tipping axis of the vehicle, and counterbalancing means co-operating with the lid, the parts being so constructed and arranged that when the vehicle is in its travelling position the lid is counterbalanced, and when the vehicle is tipped the counterbalance supplements the action of the lid to open the mouth of the lid automatically. The lids 16 are hinged to longitudinal rods 20, each with a lever 22 connected to a counterbalancing spring 23. The other ends of the levers 22 are each connected by a link 24 to a controlling lever 25 attached to a push bar extending along the side of the vehicle. The operator may open the lid by pressing the bucket or bin of refuse against the push-bar; in a modified construction, the lid may be opened by depressing the push bar. In the arrangement described three lids are arranged along each side of the vehicle, hinged on a common axis, and the pushbar extends along the length of two of the receptacles. To open a selected lid the rod 20 is slidable by a hand-lever 28, pivotally mounted at one end of the vehicle and provided with a forked end 29 engaging between flanges 30, Fig. 3. The rods 20 carry tongues 21 which may be brought into engagement with either the centre lids or the rearward lids. The rods are of square cress-section at the other ends to make operative connection with the levers 22.

Title: Improvements in multiway hydraulic valves and sealing means therefor
IPC: F15B13/06
Filed: 1953-04-23
Abstract: 783,879. Valves. SEETRU, Ltd., and VARGA, O. H. Dec. 3, 1953 [April 23, 1953], No. 11158/53. Class 135. In an hydraulic control valve having two or more valve plungers reciprocable in parallel bores and in which each plunger selectively controls three or more ports, each plunger is formed with grooved lands in each of which is mounted a rubber or rubber-like sealing ring. As shown, a casting 60 is formed with eight parallel bores, each of which slidably mounts a plunger 15. Three bores, 61, are arranged in a rear row and connected to separate fuel tanks through supply and return connections 63, 64 and five bores, 62, are arranged in a front row and connected to separate engines through supply and return connections 72, 73. Interconnecting ducts 69, 70 are common to all the bores. On the raising of a rear plunger each of which has four grooved lands with a sealing ring, the tank associated therewith is connected to the ducts 69, 70. On the raising of a front plunger, each of which has three grooved lands with a sealing ring, the ducts 69, 70 are connected to the engine associated with that plunger. The arrangement being that any tank may be selectively connected to any engine. For convenience in manufacture the casting may be split at right angles to the plunger bores into several separate parts, the individual bores may be formed as spigots and sockets which fit together when the casting is bolted up or alternatively the alignment of the bores may be achieved by dowels or fitted bolts.
